Title: Safety device in space heater
Inventor: KISHIZOE YOSHIHIKO
IPC: F23N5/26
Filed: 1990-10-26
Abstract: PURPOSE:To secure safety and improve the handling easiness of the above device by making a display section perform an informing action when a value measured by a timer is beyond a set value and suppressing the maximum quantity of combustion of a burner to a value that is lower than the previous value by a certain value. CONSTITUTION:A blower 5 is ON, and then the fuel is sent to a burner 1 as soon as an ignitor 4 starts action, and the combustion starts. Hot air thereby circulates in the room and space heating is carried out. In these conditions the burner is used for a long time, and when dusts accumulate in a filter 8 as when the time of combustion reaches 1000 hours in total and the maintenance service is required, the lighted LED 23 begins to flash as an action to inform the user of the request of cleaning of the filter 8. And, if the filter 8 has its meshes clogged, the blast volume from the blower 5 is reduced, and there is possibility that the space heater is overheated, and/or incomplete combustion occurs. For safe operation, therefore, not only the action of the informing is required but also the quantity of combustion of the burner 1 is reduced to, for instance, about 50% and the combustion is continued.

Title: Heating tool structure for outer lead bonding and bonder
Inventor: SONEHARA HIDEAKI
IPC: H05K3/34
Filed: 1988-11-17
Abstract: PURPOSE:To enable uniform bonding by differentiating the thicknesses of the parts in contact with the FPC(flexible printed circuit board) of a heating tool for thermally press-adhering the FPC between circuit boards having two types of different materials with the materials of both the boards. CONSTITUTION:The thickness t1 of a heating tool 4 of the side in contact with the bonded part 8 between a board 1 having high thermal conductivity and a FPC 2 has a relationship of t1>t2 to the thickness t2 of a heating tool 4 of the side in contact with a board 5 having low thermal conductivity and the FPC 2. When the same bonding conditions are set, heat is accumulated at the bonded part on the side of the substrate having the low thermal conductivity and heat is dissipated at the side of the substrate having the high thermal conductivity so that the heat quantity is insufficient. Thus, the thicknesses of the parts in contact with the position to be connected are varied in one heating tool due to the difference of the thermal conductivities of the boards. Thus, the bonding condition of the boards 1, 5 can be made uniform.

Title: Earth retaining construction method
Inventor: KATO CHIHIRO
IPC: E02D17/04
Filed: 1994-10-31
Abstract: PURPOSE: To prevent the deformation or destruction of an earth retaining wall for coping with heaving by continuously constructing an underground wall between earth retaining walls constructed in a ground, and supporting the earth retaining wall through the underground wall, and excavating the ground between the earth retaining walls together with the underground wall. CONSTITUTION: An earth retaining wall 10 such as a continuous underground wall or the like is constructed at a fixed depth in a fixed ground. An underground wall 20 is continuously constructed in the ground between the opposite earth retaining walls 10. Since both the ends of the underground wall 20 abuts on the earth retaining wall 10, earth pressure P acting on the earth retaining wall 10 is transmitted to the underground wall 20. In this case, since the earth pressure P severally acts on the underground wall 20 in mutually opposite directions, it mutually sets off. Thus the deformation of the earth retaining wall 10 can be avoided before excavating the ground between the earth retaining walls 10, and destruction resulting from the above deformation can thereby be prevented.
